I'm new to Glocktalk and reloading, but this is an Excel 2007 spreadsheet I made up to look at the cost of reloading vs. buying cheep ammo.
I eventually decided to reload, and added features to track that spending as well. A lot if it is based on named ranges of cells. If you not familiar with that, updating with your own information may not work well.
This was not intended as anything beyond my own use, but perhaps it will be useful to some out there that use excel. If you do not have excel, this may or may not work with OpenOffice. I have not tried it.
Something else I recently found but have not tried is Reloaders Reference
